I got it on my first try today.
2 of the spots didn't have bosses, the other 2 had the necro and monk.
However, Shield of Deflection is proving to be quite difficult in its stead.
It took me 15+ tries to get Migraine, and it seems Shield of Deflection will follow suit:
I went through 6 times so far, and 4 of those times didn't even have a boss at the first spawn. The other two, the ele and mesmer showed up.
Persistance is the key. It's frustrating and annoying to do the missions again and again just to check the spawn spots, especially considering how difficult the hench can be. (Pulling out Jade Armors/Bows from inside the radius of a Mursaat Tower is a real pain with hench. You have to run quite the distance to get them to move, and their behaviour quirks don't really help. Watch the warriors... They'll move inch by inch, because instead of leaving right away, they'll move, take damage, use healing signet, move, take damage, use healing signet, then often die from the reduced armor during Healing Signet and getting smacked hard by the Ether Seal.)
Your alternative, yes there is one now, is to get a PvP character, play and earn 3k points, and unlock it that way. 3k points and the time it takes to get them might not seem worth it, but compared to the frustration of trying to capture some skills, it may very well be. Not so much any more since they changed the SoC system, but still enough that if the system had existed in the past, I'd have unlocked Migraine that way.
It took 2 nights and part of a day to find the boss =\
